# This script undoes what the enable-host script does.  Specifically, it
# kills the dmucs loadavg daemon, and, then sends a "remove host" message
# to the dmucs server (note that a loadavg message from a machine adds
# the host to the dmucs database if it is not already there, but lack of
# periodic load average messages from a host does NOT remove the host from
# the database -- that's why we have to send a "remove host" message.
#
# Then, this script kills the distccd daemons.
#
# Arguments: 1: the name of the machine on which the dmucs server is running.
